Upgrading to a Hotfix or adding/removing applications
If you want to, for example, upgrade to a Hotfix-version of Orchestra, or if you want to add/remove one or several application(s), this is possible by using the Upgrade Wizard. For more information, see
“Upgrade Wizard and Properties File” .

If upgrading to a Hotfix, the Queue Agent database will be removed.
This procedure can be useful if your business changes so that you, for example will start using the Connect Counter application, or if you installed an application by mistake.
The following matrix shows which applications it is possible to undeploy/deploy with the use of a hotfix upgrade.

It is never possible to add/remove Central.

If you have installed a customised Business Intelligence Language Pack, or a Language Pack from the Pentaho market place, this should still work as expected, after a Hotfix upgrade, since the
pentaho-solutions/system folder remains intact after upgrade.
Application | Deploy possible | Undeploy possible | Comment |

Follow these steps:
1. In the Upgrade Wizard, select Add and Remove applications, or Hotfix upgrade, depending on what you want to do:
2. The next page shows the applications that are already installed in your system:
Here, make sure that all of the applications that you want in your system are selected.

The applications that can not be removed are greyed out.
3. Run the rest of the Upgrade Wizard, in the normal way.
